“…In this study, we observed a 98.3% prevalence of ARV infection based on ELISA similar to the ARV prevalence reported in Iran (98.3%) 18 , and higher than the prevalence reported in Romania (85.5%) 19 , Turkey (70.6 to 77.2%) 20 and Nigeria (41%) 21 . The IDEXX ELISA kit plates are coated with a whole virus lysate and detect “total” antibody response, therefore the kit is not strain-specific and highly cross reactive to a wide range of pathogenic and non-pathogenic ARV strains.…”

In recent years, emerging strains of pathogenic arthrogenic avian reovirus (ARV) have become a challenge to the chicken industry across USA and Canada causing significant economic impact. In this study, we characterized emerging variant ARV strains and examined their genetic and antigenic relationship with reference strains. We isolated 37 emerging variant ARV strains from tendons of broiler chickens with clinical cases of arthritis/tenosynovitis at commercial farms in Saskatchewan, Canada. Viral characterization using immunocytochemistry, gold-immunolabeling and electron microscopy revealed distinct features characteristic of ARV. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analyses of the viral Sigma C gene revealed genetic heterogeneity between the field isolates. On phylogenetic analyses, the Sigma C amino acid sequences of the isolates were clustered into four distinct genotypic groups. These ARV field strains were genetically diverse and quite distant from the vaccine and vaccine related field strains. Antibodies produced against a commercial Reo 2177 ® vaccine did not neutralize these variants. Moreover, structure based analysis of the Sigma C protein revealed significant antigenic variability between the cluster groups and the vaccine strains. To the best of our knowledge, this is the first report on the genetic, phenotypic and antigenic characterization of emerging ARVs in Canada.

“…To date, very few studies on seroprevalence of ARV in backyard chickens have been conducted worldwide. The present study’s findings showed that the seroprevalence of ARV is very high (94.4%), which agrees with reports from western Turkey (86.53%) (Erol & Sengül 2012 ) and Korea (100%) (Jae-Kyo et al 2019 ). Lower ARV seroprevalences were reported from Zimbabwe (3%) (Kelly et al 1994 ).…”

“…It might be happen because long-term antibody is developed as a result of constant reinfection of virus subclinically in broiler breeder [13]. Erol and Sengul [24] also observed higher antibody titer in broiler breeder against ARV in Turkey. Seropositivity of ARV was higher in the age of 4-6 weeks than other two age groups.…”

Serological detection of avian reovirus in different poultry flocks of Gazipur and Mymensingh districts of Bangladesh

Background and Aim: Avian reovirus (ARV) is a constraint to poultry industry in Bangladesh as a cause of several diseases in chickens, especially in broiler. However, the actual status of the viral infection is not known because the large-scale study is not conducted in this country. Therefore, this study aimed to check the presence and distribution of ARV-specific antibody in respect to area, types of chickens (broiler breeder, broiler, and layer), vaccination status, and age of chickens in Gazipur and Mymensingh districts of Bangladesh. Materials and Methods: A total of 276 chickens' blood samples were collected from two well-organized broiler breeder stock, seven broiler farms, and five layer farms located at two districts, namely Gazipur and Mymensingh of Bangladesh. Blood samples were collected from wing vein of the apparently healthy chickens using 3 ml of syringe and serum was harvested by keeping the syringe at room temperature in slanting position. The sera were transferred to the laboratory by maintaining the cool chain and further processing was performed by indirect enzyme-linked immunosorbent assay using ARV antibody test kit. Results: The results of serological test revealed that an average of 39.5% seropositive against ARV was recorded in chickens of Gazipur and Mymensingh districts. Among these, chickens of Gazipur district had the highest seropositivity of 50.5% than Mymensingh (30.7%). With respect to vaccination status, the seropositivity of vaccinated chickens in both areas was 100% and non-vaccinated chickens was 50.5% in Gazipur and 30.7% in Mymensingh district, respectively. However, regarding age groups, the seropositivity was higher in the age of 4-6 weeks (64.5%). Conclusion: The present serological findings showed a higher prevalence of ARV-specific antibodies in broiler birds. It indicates that the poultry industries of Bangladesh are contaminated with ARV which may naturally be transmitted to chickens either vertically or horizontally.
